RESILIEN TIRE.

Specification of Letters Patent. Patented VFeb 7, 1922.

.- .Application filed May 3, 1921. Serial No. 466,592.

VIt is an object of my invention to provide a resilient tire which shallcombine the ad: vantages of the pneumatic tire and the solid tire suchas are in ordinary use, which shallv wear well and be highly resilient,at the same time being substantially punctureproof.

Referringto the accompanying drawings which are made a part hereof andon which similar reference characters indicate similar parts,

Figure 1 is an elevation of a portion of a tire with parts broken awayas indicated by the lines A-B and C-D of Figure 2, and i i Figure 2 is asection ofthe tire on line Y 2 2 of Figure 1;

lsrs

In the drawings 10 indicates a rimof any ordinary type having anges 1-1at its sides and a clamping device 12 at the middle attached tothe rimby rivets or other ccnvenient means, the flanges and clamp beingintended toV hold in place a pair of pneumatic tires 13 of any ordinarytype here shown as elincher tires. The tires 13 encase tiretubes 14 inthe usual manner and Y the tire tubes are adapted to beinflated by meansof an air inlet 15 having a'cap 16.k This inlet at its lower endcomprises two branches which extend into operative relation to pipes 17.The pipes 17 are held in place on the rim by nuts 18 and the `branchesof inlet pipe 15 are held between nuts 18 and 19.

On their peripheral surfaces the tires 13 have enlargements 2O.V Aseries of metallic plates 21 are formed to'fit over theseen-d largementsand engage closely with both of the tires. A second series of metallicplates 22 corresponding in number to the plates 21 are formed to engageclosely the bent-up portions of plates 2l'and are' secured thereto fbeassembled in other ways.

by screws 23 passing through perforations i atthe outer ends ofgplates22 and engaging l threaded openings in the thickened parts'of plates21.V These units 22 have inclined side flanges 24 engaging the beveledlower edges of a tread, shown in the drawings as a solid endless tire 25which may be molded in place Y on the units 22 if desired or thepartsmay The tire 25 has wires 26 extending circumferentially thereof`and also has transverse slots on its v inner face :to accommodate thebulged lportions of plate 23. l Y

The tire .25 takesthe ordinary wear of the road and is made of anyordinary material, preferably rubber, and may have any desired form andstructure.

The outer tire is resiliently supported -by the pneumatic tires which onthe other'hand are protected fromwearby the solid outer tire. Theinterposed members 21 and 22 provide means for holding the tires 13 andl25.r securely in relative position and `yet are well adapted to permitrelative movement of parts by reason of their large number and theirspaced relation `to each other. lVhen the tires13 are Vdeflated tire 25may readily. be removed from the wheel .andrepaired or replaced. It willseldom be necessary vto remove parts 22, 21 and the resilient tiresk forvtheir elements 4but if it should become necessary this can also bedone without difticulty after the tire 25 has been removed. Tire 25 may,if desired, be formed insegments held on plates 22 and these segmentsmay extend over only one such plate, or over a plurality of plates, asmay be found expedient. i Having thus full f described my saidinvention, what I claim as newv and desire to secure by Letters Patent,is:

1. In a tire structure, a pair of pneumatic tires having irregularitiesat intervals on their peripheral surfaces, connecting means extendingacross said pair of tires adapted 'to engage said irregularities andprevent relative sidewise movement of the tires and a tread surroundingsaid devices and held iny matic tires having spaced raised4 portions onYtheir peripheralsurfaces, a series of metallic plates extending" acrosstwo or more of vsaid tires andphaving sockets to lit said enlargements,a tread encircling said pneumatic tires, and means for holding 'saidtreadV -against lateral movement relative to' said Y clincher tires fastthereto andv having en' plates, substantially as set forth.

4. In a'tire structure, a plurality of pneu- ,matic tires having raisedportions on their peripheral surfaces, ka series of metallic platesvextending across said tires and having `sockets to fit saidenlargements, a treadV encircling said pneumatic tires, and means forholding said tread against movement relative tosaid plates comprising asecond series of plates having portions engaging the tread Vto preventrelative lateral movement between the plates of said second series andthe tread, substantially as set forth.k

` 5. In a tire structure, a rim, a plurality of largements on theirperipheral surfaces, a series of spaced metallic'plates closely engagingsaid pheripheral surfaces and the en-V largements thereon, al Secondseries of spaced' vmetallic plates respectively aflixed to the plates ofthe' first series to prevent Arelative movement thereof and a solid tirecarried by Athe plates of said second series, substantially as setforth,

6. In a tire structure, a rim, a `plurality of' clincher tires fasttheretol and having enlargements oiitheir peripheral surfaces, a seriesof spaced metallic lplatesclosely enlargements thereon, a second seriesof plates respectively attached to the plates ofsaidj first series toprevent lateral movement, the

plates of said second serieshaving outwardly `guig'iiig saidperipheralsurfaces and theen-VV extendngflanges and a solid tiresupportedV vclamping means between the tires compris- 'ing a Aflange forengagementwith each tire to cooperate with the flanges of the rim, aplurality of' rigid spaced connecting units fei'entially of the unitsand a treadheld in supported'on said-tires and-extending across aplurality thereof, wires extending circumplace on theunits by saidWires, substantiallyV Y as set forth.

In'witiiess whereof, I have hereunto set my hand and seal atBloomingdale, NewV Jersey, this 9th dayof'April, A.D. nineteen hundredand twenty-one.
